As a matter of Patent Office practice, a specification which contains adisclosure of utility which corresponds in scope to the subject matter sought tobe patented must be taken as sufficient to satisfy the utility requirement of §101 for the entire claimed subject matter unless there is reason for one skilledin the art to question the objective truth of the statement of utility or itsscope. Assuming that sufficient reason to question the statement of utility andits scope does exist, a rejection for lack of utility under § 101 will be properon that basis; such a rejection can be overcome by suitable proofs indicatingthat the statement of utility and its scope as found in the specification aretrue.
